Roderique-Davies (2009) afirma que usar la palabra "neuro" en PNL es "efectivamente fraudulento dado que la PNL no ofrece ninguna explicación a nivel neuronal y se podría argumentar que su uso se alimenta falazmente en la noción de credibilidad científica".
$begingroup$ In case you examine just an individual case in point, it may well look like the frequency of hedging directly results the EV/Avg(Pnl), like in the specific situation you described in which hedging each and every moment proved being a lot more rewarding.
But you need to consider the issue in A much bigger photograph perception. How would hedging frequency influence the outcomes over 1000s of simulations?
$begingroup$ Unsure it is a valid question! Gamma p/l is by definition the p/l on account of recognized volatility remaining diverse from implied.
The net outcome of everything is enhanced delta hedging frequency does just contain the smoothing effect on P/L about prolonged plenty of time horizons. But such as you show that you are subjected to one particular-off or rare mean reversion (or development) outcomes, but these dissipate around substantial samples.
La PNL parte de la premisa de que las personas tienen dentro de sí mismas los recursos necesarios para realizar cambios positivos. El trabajo del terapeuta o coach es ayudar a la persona a acceder a estos recursos y utilizarlos de manera efectiva.

And this relies on the rebalancing frequency. But "predicted P&L" refers to an average over all possible cost paths. So There's not necessarily a contradiction below. $endgroup$
Por observación ocular. Observando los ojos de la persona que tenemos delante y comprendiendo los señales que nos emiten sus ojos, podemos averiguar cuál es el sistema representativo que se está utilizando en ese momento.

Owing to your past equality I recognize that the "school scenario" pnl takes under consideration the overall performance from the income investment decision of the profit built along how, that may be $PnL_1rdelta t$.
$begingroup$ I estimate every day pnl on a CDS position using the spread adjust situations the CS01. Nonetheless I want click here to estimate the PnL for a longer trade which has gone from a 5Y CDS to your 4Y with associated coupon payments. Allows consider:
The PnL in between $t$ and $T$ may be the sum of all incrementals PnLs. That is definitely if we denote by $PnL_ uto v $ the PnL in between moments $u$ and $v$, then
The sensitivities system [two] includes 1st calculating selection sensitivities often known as the Greeks as a result of prevalent exercise of symbolizing the sensitivities employing Greek letters.
PnL unexplained is thus a metric that, when huge, might spotlight instances where the chance variables labeled for your dangerous posture are incomplete, or the versions employed for sensitivities calculations are incorrect or inconsistent.[four]
